The EN 1062-7-2004 standard specifies methods for determining cracking shielding characteristics of coatings and varnishes for films and coating systems used on exterior masonry and concrete surfaces. The standard focuses on evaluating the performance of coatings and coating systems against cracking on infrastructure surfaces, in particular their ability to effectively cover and bridging minor cracks. The standard describes in detail the test procedures, test conditions and Measuring methods to ensure that coatings maintain good protection in the event of cracking and extend the service life of the building. Through the implementation of this standard, it can help the construction industry to choose a suitable Coating System to improve the durability and crack resistance of buildings and ensure the long-term Stability of external structures.
